ICE-PICK.

Specification of Letters Patent No. 23,969, dated May 10, 1859.

.To all whom 'it may concern:

Be it known that we MILTON WVHITE, HOWARD WHITE, HENRY T. VHITE, and JOSEPH VHITE, of Philadelphia and State of Pennsylvania, have invented a new and Improved Ice-Pick, and do hereby declare the following to be a full and exact description of the same, reference being had to the annexed drawings, making a part of this specification.

A, is a metallic ball which screws upon the metallic tube B, B, and at its lower extremity is a slight elevation as shown at CZ d.

C C is a pointed metallic stem. The elevation l lis on the inside of the tube. On the stem C C is a protuberance shown at c. This protuberance catching` upon the elevation d (Z prevents the stem C C from falling out of the tube B B. The ball A, immediately over the upper extremity of the tube is hollow as shown at 7 The lower extremity of the tube, G Gr is made so that it may screw upon the tube B B, but this is not material. l

The mode of using our improved ice-pick is as follows: The point of the stem is placed upon the ice (the whole instrument being supported by holding it by the lower part of the stem). The ball A and tube B B is then raised and left to fall forcibly. The ball striking upon the head of the stein drives it into the ice which is consequently fractured.

The advantage of our improved ice pick is that a better fracture and less waste of ice is produced.

Having thus described our improvement what we claim as our invention and desire to secure by Letters Patent is- The combination of the ball A and tube B B sliding upon the stem C C in such a manner that the blow may be struck upon the head of Athe stem substantially as above described.
